Math Problem Statement
onstruct a truth table for the statement. left parenthesis tilde p logical or tilde r right parenthesis left right arrow left parenthesis tilde r logical or q right parenthesis Question content area bottom Part 1 Construct a truth table for the statement. Fill in the blanks below. p q r (tilde p logical or tilde r) left right arrow (tilde r logical or q) T T T ▼ T F ▼ F T Upper F ▼ T F Upper F
Solution
To construct a truth table for the given statement , we will create a table with all possible combinations of truth values for , , and . Then, we will compute the values of the sub-expressions step by step, which includes negating variables and evaluating the logical disjunction (OR, ) and biconditional () operations.
Key Symbols:
- : Negation of
- : Logical OR
- : Biconditional ("if and only if")
Step-by-step process:
- Column 1-3: Assign all possible truth values for , , and .
- Column 4: Compute and , then find the value of .
- Column 5: Compute , then find the value of .
- Column 6: Evaluate the biconditional .
Let's build the truth table step-by-step.
T | T | T | F | T | F |
T | T | F | T | T | T |
T | F | T | F | F | T |
T | F | F | T | F | F |
F | T | T | T | T | T |
F | T | F | T | T | T |
F | F | T | T | F | F |
F | F | F | T | F | F |
Explanation:
- , , and : The first three columns list all possible combinations of truth values for , , and (T = true, F = false).
- : This column shows the result of the disjunction (OR) between the negation of and the negation of .
- : This column shows the result of the disjunction (OR) between the negation of and .
- : The biconditional checks if the two sub-expressions have the same truth value. If they do, the result is T (True); otherwise, it is F (False).
